A controlling device has a moveable touch sensitive panel positioned above a plurality of switches. When the controlling device senses an activation of at least one of the plurality of switches when caused by a movement of the touch sensitive panel resulting from an input at an input location upon the touch sensitive surface, the controlling device responds by transmitting a signal to an appliance wherein the signal is reflective of the input location upon the touch sensitive surface.

A pushbutton switch according to one or more embodiment may include a first attachment, an operable portion, and a detector. The first attachment has a loose-fitting hole to loosely receive a locking magnet. The detector includes a switcher that selectively places an attraction magnet or a repulsion magnet at a position facing the locking magnet.

A protection unit, including a power switching device, with a mechanical switch. To improve the multipurpose nature of the power switching while making lockout easier and more reliable, provision is made for the power switching device to include an electrical actuator actuating the mechanical switch and being controlled by an electronic control unit, which is itself powered via an auxiliary switching device. A lockout system with a lock is provided, which, in a lockout configuration, mechanically keeps the mechanical switch and the auxiliary switching device in an isolation configuration, and, in operating configuration, allows the mechanical switch and the auxiliary switching device to move between the conduction configuration and the isolation configuration.

A runway light control including a relay switch for connecting to a common conductor and a push-to-talk conductor of the aircraft communications system. The control includes a microcontroller connected to the relay switch and an intensity selector assembly connected to the microcontroller. The selector assembly has first, second, and third intensity selectors. The microcontroller is programmed to intermittently close the relay switch a first preselected number of times when the first intensity selector is actuated to signal the automated variable intensity runway light control station to select a first runway light intensity at the airport. The microcontroller is programmed to close the relay switch a second number of times when the second selector is actuated to select a second runway light intensity. The microcontroller is programmed to close the relay switch a third number of times when the third selector is actuated to select a third runway light intensity.
